    dct:description "This dataset stores geophysical, transport and chemical data collected during a six-month experiment involving CO2-brine-rock interaction with stress, at reservoir conditions. The rock used for the tests was manufactured in the National Oceanography Centre, Southampton, following the procedure described in Falcon-Suarez et al. (2019). The aim was to study the coupled hydro-mechanical-chemical (HMC) phenomena that occurred in sandstone reservoirs containing carbonates, when interacting with CO2 during Carbon Capture and Storage (CCS) operations. The dataset includes results from two brine-CO2 flow-through tests and three intercalated hydromechanical assessments, where elastic (P- and S-wave velocities and attenuations), transport (bulk electrical resistivity and permeability) and axial strain data were collected and analysed together with basic petrophysical properties. Results from a reactive simulation developed using free-software PHREEQC (Parkhurst and Appelo, 2013) are also included. The tests were conducted in the high-pressure, room-temperature (20 C) experimental setup for multi-flow-through tests in the Rock Physics Laboratory at the National Oceanography Centre, Southampton (NOCS), from 2021 to 2025, as part of the projects GASRIP, EHMPRES and FOCUS (NERC grants NE/X003248/1 - FAPESP-EHMPRES, NE/X006271/1 - FOCUS and NE/R013535/1 - GASRIP).
